sometimes aesthetics


overides the principle of minimizing driver vertical spacing. If you position the woofer at the top of the enclosure, with equal distance from each side and top, it will look "good" and be pretty close to the horn on top.
Since you are not "losing" any front baffle space to a h-290 cutout, you have a large, open area in the lower portion of the front to symetrically place a round port. If using a rectangular port, it could be resized to look nice as a "slot" opening across the lowest portion of the front baffle. Cerwin Vega had something similar exiting from the rear of a few enclosures.
But a round port, spaced equal from the sides, and centered between the lower edge of the woofer and bottom of the baffle...pretty basic, a simple low tech look that does everything right. Visually, YOU have to be pleased. I have even gone as far as cutting out "mock driver and port holes" from black paper, and taping them to a front baffle, then look at them for a few days. Sam
